The Rolex Submariner, a name synonymous with diving prowess and enduring style, boasts a rich history spanning decades. While each era holds its own unique charm, the Submariners produced during the 1970s represent a fascinating chapter, a bridge between the rugged tool watches of the earlier years and the more refined pieces of the later decades. This period saw subtle yet significant changes in design, materials, and movements, shaping the character of the Submariner we know and love today. Understanding the nuances of these 70s Submariners requires a closer look at their evolution, their current value, and their place within the broader context of Rolex's production during that decade.
The Legacy of the 6538 and its Influence on the 70s Submariners:
Before delving into the specifics of the 1970s, it's crucial to understand the foundational model that laid the groundwork: the Rolex Submariner 6538. Introduced in 1956, the 6538 marked a significant evolution, featuring a thicker case than its predecessors. This thicker case, a design element that would persist and evolve throughout the 70s, provided enhanced durability and water resistance, vital attributes for a professional diver's watch. The 6538's robust construction and reliable performance cemented its status as a legendary diver's tool, and its influence is clearly visible in the Submariners that followed it in the 1970s.
The 1970s Submariner: A Transition Period:
The 1970s witnessed a gradual evolution of the Submariner design. While the core elements remained – the iconic oyster case, the unidirectional rotating bezel, and the highly legible dial – subtle alterations marked the shift towards a more refined aesthetic. These changes weren't dramatic overhauls but rather a series of refinements, reflecting Rolex's ongoing commitment to both functionality and elegance.
One noticeable change was the introduction of new bracelet variations. While the riveted oyster bracelet remained a staple, Rolex also introduced the more modern solid-link bracelets, further enhancing the watch's comfort and durability. The evolution of the bracelet reflects the broader trend in watchmaking during the 70s, moving towards more integrated and refined designs.
The dials of 70s Submariners also tell a story of subtle transitions. The luminous material, initially radium, was gradually replaced by tritium, offering improved luminosity with fewer health concerns. The font styles and the placement of text on the dial also underwent slight modifications throughout the decade. These seemingly minor details are significant to collectors who can identify specific production years based on these minute variations.
Reference Numbers and Their Significance:
The Rolex Submariners of the 1970s are identified by their reference numbers, each denoting specific variations in case size, movement, and features. Understanding these reference numbers is key to appreciating the nuances of each model. For example, certain reference numbers indicate the presence of a specific movement, such as the calibre 1520 or 1530, both known for their reliability and accuracy. The case size also varied slightly throughout the decade, with subtle differences in lug-to-lug measurements and overall dimensions.
